Chemical composition and antioxidant and antifungal properties of Mentha x piperita L. (peppermint) and Mentha arvensis L. (cornmint) samples

Abstract

Essential oils and infusions from commercial peppermint sachets (CPS), and noncommercial genuine peppermint (NCP) and cornmint (NCC) samples were analyzed by GC/MS and LC/MS. Minimum inhibitory concentration (MIC) of mint oils against Fusarium moniliforme, Aspergillus niger and Aspergillus fumigates was determined. Antioxidant potential was monitored by total phenolic content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and soybean oil oxidation tests. CPS and NCC oils had lower menthofuran content than NCP. Mint oils did not show a uniform standard of antifungal activity and they had the modest reducing ability. CPS and NCC infusions showed higher IC50 and lower TPC than NCP ones. In the soybean oxidation test, mint oils presented prooxidant behavior. CPS infusions showed antioxidant potential significantly (P<0.05, Tukey) lower than that from NCC and NCP infusions. NCP infusions were more efficient in delaying propagation reaction than NCC ones. This may be attributed to higher amount of rosmarinic acid and hesperidin in NCP.

Ethnomedicinal, phytochemical and pharmacological updates on Peppermint (Mentha × piperita L.)—A review

“…In the micro‐dilution method, MIC values of 2.50 and 1.00 (mg/ml) respectively. Similarly, anti‐fungal application of oils or extracts results were shown in the previous literature representing high sensitivity of M. × piperita against many of fungal strains Sacchromyces cerevisiae (Sandasi et al, ; Tyagi & Malik, ) Candida albicans ( Pramila et al, ; Tyagi & Malik, ; Zaidi & Dahiya, ) , Fusarium oxysporum (Desam et al, ; Tyagi & Malik, ) , Mucor spp (Tyagi & Malik, ), Aspergillus niger (Hussain et al, ; Mahboubi & Kazempour, ; Nilo et al, ; Tyagi & Malik, ), Aspergillus flavus (Hussain et al, ; Tyagi & Malik, ) and Penicillium digitatum (Tyagi & Malik, ). Anti‐fungal activity is depicted in Table .…”

“…Flavones (luteolin, luteolin O ‐diglucuronide, luteolin O ‐glucuronide, luteolin 7‐ O ‐ β ‐glucuronide, luteolin 7‐ O ‐rutinoside and isorhoifolin), flavanones (eriodictyol, naringin, eriodictyol‐glycopyranosyl rhamno pyranoside, naringenin7‐ O ‐ β ‐glucoside, hesperidin and eriocitrin), methoxyflavones (gardenin B, 5,6‐dihydroxy‐7,8,3,4‐tetra methoxy flavone and salvigenin) and flavonols (catechin, rutin, [−]‐epicatechin, quercetin, quercetin‐4‐glucoside, kaempferol 7‐ O ‐rutinoside and myricetin O ‐glucoside) isolated and identified from M . × peperita (Fecka & Turek, ; Hoffmann & Lunder, ; Kapp et al, ; Krzyzanowska et al, ; Nilo et al, ; Voirin et al, ). The phyto‐constituents of these flavonoids are shown in Figure .…”

“…Peppermint leaves and oils have been used for anti‐fungal applications in numerous previous investigations. Nilo et al () described the activity of the essential oil (2–5 mg/ml) obtained from leaves of M . × piperita has been reported to inhibit the growth of Fusarium moniliforme, Aspergillus niger and Aspergillus fumigatus with 2.50 ± 0.0, 1.25 ± 0.0 and 2.50 ± 0.0 mg/ml respectively.…”

Bioactive components of peppermint (Mentha piperita L.), their pharmacological and ameliorative potential and ethnomedicinal benefits: A review

“…found almost 11 to 12 types of fungus (including Candida albicans, Trichophyton mentagrophytes, Aspergillus fumigatus etc.) against which peppermint oil has shown significant inhibitory activity [23] According to Nilo et al (2017) the extract of peppermint leaves has fungicidal effect against the aggrandizement of some fungus including Fusarium moniliforme, Aspergillus niger and Aspergillus fumigatus [24] . According to Hussain et al (2010), peppermint oil was found to show an inhibitory effect on Aspergillus niger, Aspergillus flavus, Rhizopus solani and Fusarium solani [25] .…”
